Question

50·Ixl-0,1·IyI, если х=-0,2; у=40

Answer 1

50*0,2-0,1*40=10-4=6

Answer 2

To find the value of the expression 50·|x|-0.1·|y|, we need to substitute the given values of x and y into the expression and perform the calculations. Given that x = -0.2 and y = 40, let's proceed with the calculations:

|x| means the absolute value of x, which is the distance of x from zero on the number line. So, |x| = |-0.2| = 0.2.

|y| means the absolute value of y, which is the distance of y from zero on the number line. So, |y| = |40| = 40.

Now, let's substitute the values into the expression:

50·|x| - 0.1·|y| = 50·0.2 - 0.1·40

Now, perform the arithmetic:

50·0.2 = 10 0.1·40 = 4

Therefore, the final result is:

10 - 4 = 6

So, 50·|x| - 0.1·|y| = 6 when x = -0.2 and y = 40.
